Application filed March 15, 1909. Serial Eta-483,649.

To all whom it may concern:

Be it known that 1, WILLIAM H. DECKER, a citizen of the United States,residing in the city of Syracuse, in the county of Onondaga and State ofNew York, have invented a new and improved Means for Holding BarreLHeadsin Place, ofwhich the following is a specification;

My invention relates to barrels, or containers formed of paper pulp, andmore particularlyto that class of barrels the bodies of which are formedby winding paper pulp in superposed layers upon abilged mandrel, wherebybilged barrel bodies of this material are produced. Such barrel bodiesare wound upon collapsible mandrels, and after such a barrel body iscompleted and removed from the mandrel, it is difiicult or impossible toefficiently secure the-heads therein in any manner heretofore known,without straining and weakening the barrel body. To the end of providinga simple and ei'licient means of securing and holding the heads in suchbarrels, I secure the engagement of a holding device with the barrelbody by winding the barrel body in the first place upon a metal band orhoop so shaped as to provide an internal seat for the barrel head, andadapted to be folded or turned down upon the outside of the barrel head,whereby it is securely held in its place against pressure in eitherdirection.

My invention will be best understood by reference to the accompanyingdrawings, which illustrate an embodiment thereof.

Figure IV of the drawings shows a longitudinal section of a portion of acollapsible mandrel with the metal band by means of which the barrelhead 1s held in place, and a portion of a barrel body wound thereon;

Fig; 2 shows a longitudinal section of a portion of a barrel bodywiththe metal band apart from the mandrel; Fig. 3 shows a longitudinalsection of one end of a barrel with its head in position, and a portionof the metal band turned down to hold the head in place; Fig. 4 shows asection of the metal band separate from the barrel; Fig. 5 shows anelevation of a collapsible mandrel, and Fig. 6 a preferred form ofbending the band upon the outer surface of the barrel head.

Referring to the drawings, A indicates a band or hoop of suitablematerial, such as thin sheet iron or steel, of such circumferonce as tofit the interior of the end of a Specification of Letters Patent.Patentedliovdgll fi i i .Y

groove, a, forming on the other side-acornsthe barrel body is wound.Themandrel, B, is provided with a circumferential groove,

6, of such size and shape as torecei've the rib, a, and so located thatwhen the barrel body is wound on the mandrel, the rib, a, bemg in" thegroove, Z), the part a, of the band, A, Wlll project somewhat beyond theendof the barreh 4 In order'to engage the band, A, with the barrel body,the mandrel, B, is partially collapsed, and the, band, A, placedthereon, the rib, a, being set in the groove, b, the mandrel is thenexpanded and the barrel body, C, iswound thereon in the usual waypartially overlapping the band, A, until-it is. of the desiredthickness. body is wound the soft pulp composing it is forced somewhatinto the groove, a, thus forming a rib upon the interior of the barrelbody engaging therewith, and is also pressed upon the upstanding inneredge of the band, A, so that this edge is embedded in the material ofthe barrel body, or tightly pressed a ainst its inner surface, wherebyawatertig 11; joint is formed. The mandrel is then collapsed and thebarrel body, C, with the band, A, in place therein is removed.

As the barrel As the pulp composing the barrel body dries the barrelbody contracts upon the band, A, so that in this way, as well "as by.the engagement of the proof engagement between the band and the interiorof the "barrel body, but also covers the rough edge which the band wouldotherwise presenton the interior of the barrel, and avoids the presenceof any crevice in which the contents of the barrel might lodge. .Thebarrel head, -D, is then put in place, its'inner surface being seatedagainst the rib, a and the flange, a is turned down upon the outersurface of the head, as shown in the upper part of Fig. 3, or in Fig. 6.

In Fig. 3 of the drawings I have shown the flange, a of the metal bandturned .somewhatwithin the end of down flat upon the barrel head, as maybe this form of construction the flange, (1, is

headed or turned over in such shape that the outer edge of the flange,(4 meets the outer surface of the barrel head at substantially a rightangle, and is preferably pressed some what into the barrel head. Thusnot only is the barrel head held more firmly a ainst pressure fromwithin thebarr'el, but a iquid tight joint is provided, thus adaptingthe barrel to contents of any nature. In this case also the parts are sorelatively located that the outer surface of the barrel head is thebarrel body, thus providing a chime to the barrel, and enabling the beadof the flange, (1, to lie flush with or below body. In order to removethe barrel head it is only necessary to turn up the turned down part ofthe flange, (1 and the head can then be readily lifted out. While I haveillustrated the application of the band, A, to one end of the barrelonly, it will be evident that a similar band is to be applied in thesame way, and at the same time, to the other end of the barrel body, forsecuring the head therein.

Evidently the form and proportions of the band, A, may be varied withoutdeparting from the nature'of my invention, as it is essentialonly thatthe band shall be firmly engaged with the barrel body, and shall presenta flange which can be turned down upon the exterior of the barrel head,and I therefore do not limit myself to the precise form shown in thedrawings variations of which will readily occur to t ose skilled in theart. v

What I do claim as new and desire to secure byv Letters Patent is:

1. As a means of securing heads in barrels, a metal band in engagen'iontwith the interior surface of the outer edge thereof turned down upon theouter surface of the head, substantially as set forth.

2 The hereinbefore described means of securing in place the heads ofpaper pulp barrels which consists of a grooved and ribbed band intoengagement with which the barrel body is forced in the process ofconstruction while in a plastic state, and which the end of the barrelthe barrel, and present-v mg a seat for the inner surface of the head,-I and having is adapted to be turned down upon the exterior of thebarrel head, substantially as set forth.

3. As a means for securing heads in barrel bodies, a metal band having acircumferential groove in engagement. with the inner surface of thebarrel body, a projection providing a seat for the inner surface of thebarrel head, and a portion projecting beyond the end of the barrel body,and adapted to be turned down upon the head, subslantialtv as set forth.

4. As a means of securing barrel heads in place, a metal band providedwith a groove engaged with the interior of the barrel and acorresponding rib presenting a seat for the head, and having its inneredge embedded in the inner face of the barrel body, substantially as setforth. I

5. As a means of securing barrel heads in place, a metal band presentinga seat for the head on the interior of the barrel, and having its outeredge bent over so as to meet the outer surface of the head at an anglethereto, substantially as set forth.

(3. As a means for securing barrel heads in place, a metal bandpresenting a s at forthe head on the interior of the barrel, and havingits outer edge embedded in the exterior of the barrel head, whereby awater tight joint is formed between said band and said head,substantially as set forth.

As a means for securing barrel heads in place, a metal band secured tothe interior of the barrel body, presenting a seat for the head on theinterior of the bairehhaving its inner edge embedded in the innersurface of the barrel body, and its outer edge embedded in the exteriorof the barrel head, whereby a liquid tight joint is formed between theinterior and exterior of the barrel, substantially as set forth.

8. As a means for securing barrel heads in place a metal band inengagement with the interior of the barrel body and forming a. waterproof joint therewith and having its outer edge in engagement with theexterior of the barrel head, substantially as set forth.

In testimony whereof, I have hereunto subscribed my name, this 10th dayof March, a. 1)., 190a.
